Solar Panel Roof Mount Angle

An optimum tilt angle and orientation of your solar panels on a flat roof will ensure top energy production performance of your system.

Solar panel roof mount angle.

These angles will give you the best overall output over the course of the year if you re going for a fixed installation. If your latitude is between 25 and 50 then the best tilt angle for summer is the latitude times 0 93 minus 21 degrees. Tilt the panels to your latitude. Ideally a fixed roof mounted solar energy system should be at an angle that is equal to the latitude of the location where it is installed.

While the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face. In case the roof is very steep you may not be able to get the most optimal tilt angle for the panel especially if it is lower than the angle of the roof. Tilt the panels to your latitude plus 15. Solar panel roof mounting system supply design.

On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. The best tilt angle for winter is the latitude times 0 875 plus 19 2 degrees. For the best results solar panels should be oriented towards the south. In this case a fixed roof mount is the easiest and most cost effective option.

For instance in the san francisco bay area the best solar panel tilt angle is between 22 23 degrees. If you are able to adjust the angle of your solar panels a few times per year here is the adjustment schedule we recommend. However pitch angles between 30 and 45 degrees will work well in most situations. For los angeles a solar panel tilt of 19 degrees works the best.

Solar electric supply carries a complete line of solar panel roof mounts for residential and commercial solar systems. Solar panels should be tilted toward the sun to maximize their production. If your latitude is outside this range see other situationsbelow. Tilt the panels to your latitude.

Overall the angle of your rooftop has less impact on solar panel performance than the direction your roof faces. All of the components we carry feature weatherproof aluminum or stainless steel components for corrosion resistance. This is because the sun is always in the southern half of the sky in the northern hemisphere. Since solar panels are more productive when the sun s rays are perpendicular to their surfaces the certainly best orientation is the one directly true south azimuth angle 180.

At this level the solar panel can lie flat on the roof and get enough sunlight to produce enough electricity. Most roofs have an inclination of 30 to 40 degrees. This table gives some examples.
